HOSE AND TUBE cLAMrQ Application filed January 17-, 1927. serial no. 161,575.

An object of this invention isto provide a. light, cheap, simple, easily made clamp that is adapted to be used in securing a hose or tube of yielding or compressible material to a rigid nipple, as in the case of applying a rubber hose connection between the-radiator and the engine. of an automobile.

Other objects are ready application, tight ening, loosening arid adjustment of the clamp with respect to a compressible hose or tube onanipple. I

This invention comprises a U- sh-ape yoke having a central bridge or head and an orifice through the bridge, and having legs extending parallel .-to each other-from the ends of said bridge and terminating in crotches; a collar movable 'edge'wise between the le s and adapted to fit upon a nipple-supporte compressible tube; a threadedstem fixed to the edge of the collar and extending through the orifice; and a nut on the stem outside said yoke adapted to act 11 on'the yoke to move ing drawing, the sub'oined detailed ma is invention.

the stem and collarre ative to the crotches, and to dispose the collar entirely within the yoke when the nut is adjusted in one direction so as to protect the said 'collar against distortion when they same is in extended posi tion and to compress the tube onto the-nipple and between said nipple, and the crotches.

A feature of the invention is the construction of the yoke from a simple sheet metal stamping provided with -a central hole, and with terminal arcuate notches,.to fit upon and compress the yielding tube-or hose;

Other objects, advantages and features of invention may appear from the accompanydescription and the appende claim.

The accompanying drawing illustrates the Figure 1 isan elevation of a hose clamp constructed in accordance with this invention tracted position of the-collar and its stem.

Fig. 2 is aside elevation partly in section on line :c'f, Fig. 3, showingthe compressible tubing clamped on a connection nipple.

l The yoke may be formed of a sheet metal stamping l0 and said stamping may be'bent alongarallel lines 11 equally spaced from the ori ce 2, and the stamping is thus brought outside the yoke, adapted 4 to act between the bridge 1 and the stem to operated stem 6, conform to one half of they compressible tube-8 on the -non'compressible nipple "9; and a likeoflice is performed by the crotches-A; on opposite sides of the collar as said ring is drawn tightagainst the compressible tube.

The arcuate portionsof the crotches, practically conform respectively in'radius to the radius of the proposed compressed portion 12 of the hose 8. p The clamps will be of difi'erent sizes to accommodate the different diameters of hose 1 and the collar 5 is' of such diameter that it fits tightly upon the compressible tube or hose 8.

In practical manufacture the oke may be made from the stamping 10 of s eet metal as brought into parallelism' as in Fig.5, by bendlng along the lines '11".

illustrated in Fig. 6, the cfotches being In practice the clamp is put into use serting the' tube or hose throughthe collhr 5' and then. bringing the yoke into position with the'threa d stem 6 inserted through without causing much, if any compression of the tube.

tially of semicircular form plus tangential terminals 14 that form guides between which the hose or,tube may be forced thus to afiord a preliminary incipient compression of the hose ortube on opposite sides of the nipple as the hose enters the crotch. The stem 6 is of a length greater than the space between the crotch and the bridge so that the stem may protrude from the bridge to receive the nut before the crotch is tight on the hose.

By providing yoke 4 with elongated legs provision is made for disposing thecollar 5 entirely within the yoke, as illustrated in.

dotted lines in Fig. 1, when the nut is adjusted in one direction so as to protect the collar against distortion when the same is in extended position. A a The lateral edges of each leg 3 of th stamping 10 as shown in Fig. 6 diverge from each other to form obtuse angles 15 with the bridge 1 and practically mark the ends of the parallel bending lines 16 which are equidis-- tant from the orifice 2, and at which lines. the stamping is thus adapted to be bent to form the completed yoke; and the st'ampings may be made in large quantities and kept flat for storage and transportation until it is desired to make up a batch of the clamps; whereupon, by simply bending the 'stampin s at the bending lines 16, and setting the end with a suitable die, not shown, the yoke is completed. 7

I claim The clamp set forth comprising a U-shape yoke having a central bridge and an orifice through the bridge, and having legs extending parallel to each other from the ends of said bridge and terminating in crotches; and to dispose said collar entirely within said yoke when the nut is ad'usted in one, direc- I tion; a collar movable e gewise" between the legs and adapted to fit upon a nipple-supported compressible tube; a threaded stem fixed to the edge of the collar and extending through the orifice; and a nut on the stem outside said yoke adapted to act upon the yoke to .move the stem and collar relative to the crotches, and to compress the tube onto
